Abstract
The invention discloses a method for preparing vibration damping rubber. The method comprises the following steps of plastifying 100 parts (by weight) of styrene-butadiene rubber and 20-30 parts (by weight) of natural rubber in a rubber mixing mill for 10-15 minutes, then, adding 20-60 parts (by weight) of silicon dioxide, 2-20 parts (by weight) of diethyl suberate, 1-4 parts (by weight) of anti-aging agent, 1-5 parts (by weight) of vulcanizing agent, 1-5 parts (by weight) of accelerant and 3-8 parts (by weight) of cross-linking agent, milling for 30-60 minutes at the temperature of 50-60 DEG C, carrying out extrusion molding, and vulcanizing for 50-60 minutes at the temperature of 130-140 DEG C, thereby obtaining the vibration damping rubber. Compared with the existing vibration damping rubber, the method disclosed by the invention has the advantage that the creep property of the rubber can be obviously improved.
Description
Technical field
The present invention relates to a kind of preparation method of vibration isolation rubber.
Background technology
For reducing vibration and the noise of motor vehicle, generally adopt vibration isolation rubber to reach this object, for this kind of vibration isolation rubber, there is good creep properties, otherwise will directly affect life-span and a machine safety of product, but the compressive creep index of existing vibration isolation rubber generally reaches 15-30%.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of preparation method of vibration isolation rubber.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A preparation method for vibration isolation rubber, comprises the steps:
Plasticate styrene-butadiene rubber(SBR) 100 weight part and natural rubber 20-30 weight part on rubber mixing machine 10-15 minute, then silicon-dioxide 20-60 weight part is added, suberic acid diethyl ester 2-20 weight part, anti-aging agent 1-4 weight part, vulcanizing agent 1-5 weight part, promotor 1-5 weight part, linking agent 3-8 weight part, at 50-60 DEG C after mixing 30-60 minute, extrusion moulding, at 130-140 DEG C, sulfuration 50-60 minute, obtains vibration isolation rubber.
When mixing, also add protection wax 1-3 weight part and stearic acid 1-3 weight part.
Compared with existing vibration isolation rubber, the inventive method obtains the creep properties energy that obviously can improve rubber.
